There was a post on here for treating autism, I have searched but can't find it, does anyone have it and or feedback on its effectiveness? Many thanks in advance.

Anti-diarrhea medication may help treat core autism symptoms
Loperamide binds to and activates a protein called the μ-opioid receptor, which is normally affected by opioid drugs, such as morphine. Along with the effects that you would normally expect from an opioid drug, such as pain relief, the μ-opioid receptor also affects social behavior.
In previous studies, genetically engineered mice that lack the μ-opioid receptor demonstrated social deficits similar to those seen in ASD. Interestingly, drugs that activate the μ-opioid receptor helped to restore social behaviors.
These results in mice highlight the tantalizing possibility that loperamide, or other drugs that target the μ-opioid receptor, may represent a new way to treat the social symptoms present in ASD, but further work is required to test this hypothesis.
